Smart diagnosis is a professional diagnostic service developed by Huawei to detect and diagnose mobile phone problems in real-time. The service can also help you repair your phone if it is broken.

It is an app-based diagnostic service, which means that it does not require your phone to be turned on. It can be downloaded and installed on both Android and iOS devices. It can work in the background and does not require you to do anything else.

How does it work?

The first step is to launch the app and connect it to your phone.
